Ok I usnderstand. I will definately be able to tell when I have a fish on.
Myu second question, of to which you have eluded, is what happens to fish that are too small to break the line free from the release. I remember this being a problem for me 23 years ago when I began fishing simcoe for lakers. We would set the release too hard and end up dragging a small laker for 45 mins at time. Ended up drowning the poor fish.
I guess you just have to check the board regularly to make sure you haven't caught a random perch.
